The script of the checkbox:

on mouseUp
   storeSetting "AppTrackingTransparency", the hilite of me
   set the visible of field "App Tracking Transparency Message" to the hilite of me
end mouseUp

@livecodepanos I think it would be better here to toggle the enabled of the field, rather than its visibility

@livecodeian I have updated the checkbox to do:

on mouseUp
   storeSetting "AppTrackingTransparency", the hilite of me
   set the enabled of field "App Tracking Transparency Message" to the hilite of me
end mouseUp
